Glass Beads Manufacturer and Supplier in India
Glass beads are non-metallic abrasive media used for sand blasting, shot peening, cleaning, deburring, polishing and controlled surface finishing. Their smooth, round shape produces a clean and uniform satin finish without aggressive cutting or significant dimensional change to the workpiece.
Surface International supplies industrial glass bead blasting media in different grades and mesh sizes for stainless steel, aluminium, brass, automotive parts, aerospace components, moulds, dies and precision-engineered products. Our glass beads are available in sizes ranging from 20 mesh to 325 mesh and finer, allowing users to select the correct grade according to the required cleaning action and surface finish.

Important: Grade names and exact particle-size tolerances can vary between manufacturers. The final grade should be selected after checking the required finish, workpiece material, machine type and supplier sieve analysis.
Which Glass Bead Size Should Be Used?
The correct glass bead size depends on the condition of the component and the finish required after blasting. Coarser beads create a stronger impact and are used for faster cleaning, while finer beads produce a smoother and more controlled finish.
| Required Work | Recommended Size | Suitable Grades |
|---|---|---|
| Heavy Cleaning and Strong Surface Impact | 20–60 Mesh | A, B, C |
| Rust, Scale and Coating Removal | 40–80 Mesh | AA, C, D, AB |
| General Sand Blasting and Surface Preparation | 60–120 Mesh | AC |
| Stainless Steel Satin Finishing | 70–140 Mesh | AD |
| Aluminium and Automotive Component Finishing | 100–170 Mesh | AE |
| Precision Cleaning and Smooth Cosmetic Finish | 100–200 Mesh | AF |
| Fine Shot Peening and Controlled Finishing | 120–270 Mesh | AG |
| Ultra-Fine Finishing of Delicate Components | 170–325 Mesh | AH |
| Very Fine Polishing and Specialized Applications | 270–325+ Mesh | AI, AQ |
Selection Guidance
- For faster cleaning: Select a coarse or medium-sized glass bead.
- For a smooth satin finish: Use medium-fine grades such as AC, AD or AE.
- For precision components: Use fine grades such as AF, AG or AH.
- For shot peening: Select the size according to the required peening intensity, component hardness and approved process specification.
- For delicate parts: Start with a fine grade and lower blast pressure, followed by a test sample.
Applications of Glass Beads
- Sand Blasting: Removes light rust, oxidation, scale and surface contamination from metal components.
- Paint and Coating Removal: Removes selected coatings while limiting damage to the base material.
- Deburring: Removes small burrs and sharp edges from machined and precision components.
- Satin Finishing: Creates a smooth and uniform satin appearance on stainless steel and aluminium.
- Shot Peening: Produces controlled surface compression to improve fatigue resistance when used under approved process parameters.
- Mould and Die Cleaning: Cleans moulds, dies and tooling without aggressive dimensional change.
- Automotive Components: Used for engine parts, wheels, housings and restoration work.
- Aerospace Components: Used for controlled cleaning and finishing of precision parts according to process requirements.
- Road Marking: Specialized reflective grades improve the visibility of road lines and traffic markings.
- Decorative Finishing: Produces an even matte or bright finish on architectural and fabricated metal products.
Industries Using Glass Bead Blasting Media
Glass bead abrasive media are used across Automotive, Aerospace, Foundry, Steel Fabrication, Railway, Defence, Marine, Shipbuilding, Oil & Gas, Construction, General Engineering, Metal Finishing, Aluminium, Stainless Steel, Tool & Die, Medical Equipment, Electronics and General Manufacturing industries.
Glass Beads for Sand Blasting Machines
Glass beads are widely used in pressure blasting machines, suction blasting cabinets and manually operated blast cabinets. When accelerated by compressed air, the spherical beads strike the component and remove contamination while producing a smooth, uniform finish. The nozzle size, air pressure, media-flow setting and bead grade must be matched to the component and required production rate.
Excessive blasting pressure can fracture the beads quickly, increase dust generation and reduce media life. For best results, use clean and dry compressed air, maintain the correct nozzle distance and remove broken media and contamination through a suitable reclamation system.
Glass Beads for Shot Peening Machines
Glass beads can be used as shot peening media for selected metal components where a controlled surface treatment is required. Their spherical shape strikes the component and can introduce compressive stress at the surface, helping improve resistance to fatigue and stress-related failure.
Shot peening is a controlled engineering process. The correct bead size, hardness, blast pressure, coverage and intensity should be selected according to the component material and applicable process specification. A trial or approved procedure is recommended before full-scale production.

Frequently Asked Questions
What are glass beads used for?
Glass beads are used for cleaning, deburring, polishing, satin finishing, cosmetic finishing and controlled shot peening of metal and precision components.
Which glass bead grade is best for general blasting?
AC and AD are commonly selected for general surface preparation and satin finishing. The best grade depends on the workpiece material, initial surface condition and required finish.
Which glass bead size provides a fine finish?
Fine grades such as AF, AG, AH and AQ provide progressively finer surface finishes. A test sample should be used to confirm the required result.
Can glass beads be reused?
Yes. Glass beads can normally be recycled several times in a properly maintained blasting system. Their service life depends on blast pressure, machine condition, contamination level and the reclamation system.
Can glass beads remove heavy rust?
Glass beads can remove light rust and surface contamination. For heavy rust, thick scale or aggressive coating removal, an angular abrasive such as aluminium oxide, steel grit or garnet may be more suitable.
Are glass beads suitable for stainless steel and aluminium?
Yes. Glass beads are widely used on stainless steel and aluminium because they create a smooth satin finish without causing ferrous contamination.
What is the glass beads price per kg?
Our indicative starting price is ₹75 per kg. The final glass bead price depends on grade, mesh size, quantity, packaging, taxes and delivery location.

Glass beads are primarily used in air-operated sand blasting machines, suction blasting cabinets and controlled shot peening systems. For airless shot blasting machines and wheel-blast machines, steel shot or steel grit is generally preferred because metallic media are more suitable for blast-wheel operation and heavy-duty surface-cleaning requirements.
